Study Notes
Plant Tissue and Structures
- Photosynthates move through phloem, essential for nutrient distribution from photosynthesis.
Leaf Appendages
- Stipules are small leaf-shaped appendages located along the side of a bud, providing protection and support.
Stem Types
- Rhizome refers to a horizontal stem that grows below ground, often contributing to vegetative reproduction.
Stem Features
- A common misconception is about lenticels, which are not marks left in the leaf scar but structured pores on stems for gas exchange.
Flower Structure
- A perfect flower contains both male and female reproductive parts, allowing for self-pollination.
Underground Storage
- A tuber is an underground stem that is enlarged for storage, exemplified by potatoes, which serve as a food reservoir.
Plant Organ Classification
- Roots, stems, and leaves are considered structures of plants, each performing specific functions vital for survival.
Measuring Plant Growth
- To estimate annual growth, compare the distance between terminal bud scars; this reflects the plant's health and growth rate.
Leaf Identification
- Leaves are distinguished from leaflets by the presence of a bud at the base of the leaf, which is absent in leaflets.
Adventitious Shoots
- A watersprout is an adventitious shoot that arises from a branch or trunk, often in response to stress or injury.
Root Systems
- Fibrous roots feature a network of many secondary roots, as opposed to a single, dominant primary root, enhancing stability and nutrient absorption.
Plant Reproductive Systems
- A dioecious plant has separate male and female individuals, requiring cross-pollination for fruit and seed production.
